Are you Experiencing Hardstreaks in your Wound Roll Resulting in the Degradation of your Finished Product?

Download this paper! In this paper an improved model for computing widthwise variations in roll radius and in-roll stresses caused by widthwise web thickenss variations are described and includes the following:

A model is presented that predicts widthwise variability in wound roll radius and stresses resulting from widthwise thickness nonuniformities

The model has been verified experimentally on wound rolls of film and quantitative agreeement between the predicted and measured results was found

The theoretical and experimental technique used in its verification are described.
